For Windows 7 or Vista:

  1. Go to the Start menu.

  4. The next time you check out a book in the 3M Cloud Library App and open it, the 3M Cloud Library will use whatever Adobe ID your Adobe Digital Editions is authorized with. If you do not have ADE, it will ask if you wish to use the system-generated ID or to enter your own.

What is my “cache”? Why should I clear it? How do I clear it?

The first time you visit a site, your browser will “save” pieces of the site. Many times web developers have to make updates to the files that comprise your site in order to push a change or new feature live. If we change a file that your browser has cached, it’s going to keep serving the old, cached version of the file and you won’t see our most recent change.

The process of clearing cache differs from browser to browser. Generally speaking, look for an option to delete cache or temporary files in your browser’s administrative settings.

What is my Adobe Digital Editions ID?

This is usually the email address and password you used when setting up the account on the Adobe website where you initially applied for an Adobe Digital Editions ID. If you cannot remember your password, you can request assistance from Adobe at this website.
